  Safe Color for broadcast

  Posted by Robert Hanna on April 9, 2009 at 8:27 pm

  Hi there,
  I had a quick question. I was told by an avid editor that if I drop the “color effect” onto a video clip in my timeline, don’t adjust any of the parameters, just drop it on, then that clip will not exceed safe broadcast color limits. I was watching an avid tutorial today, and they instructed about taking the Safe Color Limiter effect, drop it on a clip or on a new video track above all my clips, set the RGB upper limit to 235 and the IRE UL to 110, and this is the way to make sure the colors are safe for broadcast. (set the 422 check box too)

  I’m wondering which is the quickest, simplest way to go using the least amount of resources (rendering and output wise), and if the assumption that the simple “color effect” will do what we need to do.
  Thanks
  Robb

  The ‘old school’ Color Effect will clip your luminance and black level to legal (rather harshly), but does nothing to make your colors legal.

  And the safe colour effect does not fix gamut errors either.

  It’ll clamp luma but no chroma. You really need to be flying by your external scopes or you are flyin’ blind.
